(A) Procedure. Following an approved primary plat, and when necessary because of time limitations, unique soil conditions or weather conditions, an approved grading plan may permit the subdivider or applicant to begin and complete grading work. The grading plan will not include final engineered drawings for streets, water lines, and sanitary sewer lines.
(B) Approval. Within ten business days from the date of submittal of the completed application, a decision shall be made in the form of an approval, approval with conditions, or disapproval. The Planning Commission designee shall sign and stamp the approved copies.
(C) Requirements. Upon the approval of the primary plat the developer of a proposed subdivision or property owner may submit a grading plan of the proposed subdivision or section thereof for review by the staff. The grading plan shall be designed by an Indiana Registered Professional Engineer or Surveyor and installed in accordance with these and other applicable regulations, and shall contain the following information:
(1) The name of the proposed subdivision or development;
(2) Name(s) and address(es) of owner or developer of the subdivision and the Indiana Registered Professional Engineer or Surveyor, responsible for all of the improvements. The plan shall be certified with the seal of the Engineer or Surveyor;
(3) The plan shall be to a scale of not less than one inch equals 50 feet. On large lots, this scale may be used to show just the graded portion of the lots and improvements. A graphic or written scale shall be placed on each sheet of the plan;
(4) The date shall be on the cover or first sheet of the plan, and a north arrow shall be on all sheets of the plan;
(5) The boundary of the subdivision or section of subdivision under review shall be indicated by a heavy, solid line on one sheet of the plan at a standard scale to show the location of section under review with other sections of the subdivision. All subdivision boundary lines shall be labeled with the bearing and distance;
(6) Location, right-of-way width, and name of all existing or recorded streets, railroads, and public and private utility easements (including drainage easements), public parks and open spaces; buildings (labeled "to remain" or "to be removed"); incorporation, county and state lines; cemeteries and other historical landmarks or natural features;
(7) Location of all existing utilities (public and private) within or adjacent to the subdivision or project area;
(8) Existing contours with intervals of not more than ten feet shall be clearly marked with elevations based on mean sea level (U.S.G.S. Datum) and location and description of benchmark used;
(9) Proposed finished contours with intervals of not more than five feet shall be clearly labeled, and related to existing contours. Maximum grade for any excavated (cut or fill) slopes shall be 2.5:1 (2.5 feet horizontal for each one foot vertical), and the design slope shall be labeled on the plan. Excavated slopes may be steeper upon report by a geotechnical engineer approved by the Commission. Disturbed limits shall be clearly identified on the submitted plan and in the field;
(10) Provide a copy of Rule 5 Permit from the Indiana Department of Natural Resources if applicable and show on the plan the location of erosion and sediment control facilities with detail drawings of each type of facility being used. The detailed soil erosion techniques or features may be referenced on the plan in accordance with the Indiana Handbook for Erosion Control in Developed Areas. All excavated areas and slopes (4:1 or steeper) shall be seeded and mulched immediately upon completion of grading of that particular slope, and rights-of-way shall be seeded and mulched immediately after the grading has been completed if road construction will not start within two weeks of grading. All seeding and mulching will be as detailed by the Indiana Department of Natural Resources, Soil Conservation techniques;
(11) Additional documentation or information, such as geotechnical studies, may be required by the Commission if an applicant is proposing to make improvements on property located near or in areas with slopes, of 20% or greater, and types of soils and geologic formations, which severely limit development.
